Ruskin Dam is a concrete gravity dam on the Stave River in Ruskin, British Columbia, Canada. The dam was completed in 1930 for the primary purpose of hydroelectric power generation. The dam created Hayward Lake, which supplies water to a 105 MW powerhouse and flooded the Stave's former lower canyon, which ended in a small waterfall approximately where the dam is today.
